Two cops assigned to an elite Queens anti-crime unit are facing an Internal Affairs probe for allegedly not properly identifying themselves after pulling over Schools Chancellor Dennis Walcott in his city-issued vehicle, officials said yesterday.

Walcott, who is credited with creating the NYPD’s “Courtesy, Professionalism, Respect” slogan in the early ’90s, complained directly to Police Commissioner Ray Kelly, sparking the investigation, officials said.

Shortly before midnight Thursday, the two cops, a police officer and a sergeant, pulled over Walcott, who was not driving, a few blocks from his Cambria Heights home, for what sources described as having tinted windows and making a left turn without signaling.

“When Chancellor Walcott asked the officers to please tell him why they had been pulled over, the officer responded that they had failed to use a turn signal. Chancellor Walcott told the officers that this was incorrect as he heard the turn signal,” confirmed his spokeswoman, Natalie Ravitz.

He also identified himself as the schools chancellor and former deputy mayor, Ravitz said.

“After the officer ran the license and plates, the officer returned the driver’s license and said they were free to go. At this time Chancellor Walcott asked the officer for her badge number,” Ravitz added. “The officers were in plainclothes and did not identify themselves.”

Neither Walcott nor his driver was ticketed.

The two officers told Internal Affairs last night they did provide their shield numbers and accused Walcott of being difficult.

” ‘You have no right to pull us over,’ ” Walcott allegedly barked according to the officer, sources said.
